Machine only runs when the start button is kept pressed down

is that the fuse in the recess in the wires I mentioned earlier? I don’t think it’s possible to get it out, I tried earlier. If it isn’t possible to change it does that mean the motor shouldn’t be run again?

Yes it will be - it's likely the thermal fuse has suffered a material failure rather than the motor suffering a catastrophic thermal event given that it runs when you bridge the black & brown wires. Don't bother digging it out, just mount a replacement with a slightly lower rating on the outside of the windings..

This is the continuation of a thread I already had going but I think it might have closed. I’am not sure how it works, so I thought I would start this new one just in case.
I have been trying to locate a blown thermal fuse in an electric motor. Today I removed the heat resistant sleeving from a brown wire and a black wire which were tied to the winding. I was expecting to find the fuse there but instead two further wires branch of from them and go down into the winding. I think the fuse must be down there but I don’t know how to get to it.

Check that connection just had a motor off a Axminster drill, the windings were alloy the multi strand was copper or tinned copper.
Alloys were corroded under the copper that had been soldered.
The copper was just wrapped round the alloy wires.
Measured ok ish but the sleeving looked as if it had got hot, cheap s.
Jet looks same as the one I repaired joint looked ok

I did suggest the same thing in the other thread about this motor

I don’t know what the fuse is rated at. I was going to mount a replacement as carbon suggested but I wanted to get a look at the old one to see if it might be written on it. Has anyone any ideas about what fuse to use?

In the photo above, you can see that I have cut some of the cords which go around the winding. Is it necessary to replace those. I put a couple of cable ties around the winding to hold the wires in place and i was wondering if it is ok to have cable ties in contact with the winding?
